Practical choice of 1H-1H decoupling schemes in through-bond 1H-{X} HMQC experiments at ultra-fast MAS

► 1H-1H dipolar decoupling greatly enhances sensitivity in solid-state 1H-{13C} J-HMQC. ► TIMES0 at 80 kHz MAS realizes a very large scaling factor of 0.90. ► Long κcsT2′ times with the aid of large scaling factors enhance sensitivities. ► J-HMQC gives cleaner and easier to interpret spectra than D-HMQC.
